Answer:

x= -5

Step-by-step explanation:

let the number be x.

2x+5= -5 ====> equation

2x= -5-5. (shifted the +5 to the other side)

2x= -10

x= -10/2 ( shifted 2 on the other side as it was multiplying with x)

x= -5

2. Tom's brother saw Muscle Fitness, which offers $20 off of the $80 fee. Membership is $15 a month plus another $5 a month.

First, solve the one time fee

$80 - 20 = $60

Next, solve the monthly fee

15 + 5 = 20

(a) The expression: Let x = month

20x + 60

(b) Remember the previous question.

<em>Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month. </em>

<em>(a) Write a expression to represent the membership cost of Platinum Gym for x months.</em>

<em>Let x = months</em>

<em>20x + 60</em><em> is your expression</em>

No. In fact, it will be the same. Waiving the $20 off the one-time fee would give the same amount of one-time payment, 60. Membership and Mandatory equipment maintenance would also add up to $20 a month.

In rhombus MOTH, angle HTM=(5x+6) degrees. If angle HMO=(12x-6)degrees, what is angle HMO?
forsale [732]

Answer:

m∠HMO=102°

Step-by-step explanation:

we know that

In a Rhombus the diagonals bisect the angles and opposite angles are equal

In this problem

Angles HMO and HTO are opposite angles

m∠HMO=m∠HTO

m∠HTM=(1/2)m∠HMO ----> because the diagonals bisect the angles and opposite angles are congruent

substitute the values

(5x+6)\°=(1/2)(12x-6)\°

solve for x

10x+12=12x-6\\12x-10x=12+6\\2x=18\\x=9

<em>Find the measure of angle HMO</em>

m∠HMO=(12x-6)°

substitute the value of x

m∠HMO=(12(9)-6)=102°

see the attached figure to better understand the problem

If Vector bought 15.6 lbs of paintballs, and altogether the balls cost $35.99.

If we want to find out how much the paintballs cost per pound, we need to  divide out the cost
